The rapid increase in digital information has seen a huge demand for computing devices particularly enterprise servers that are generally housed in data centres or co-location facilities. Data centres alone consume approximately 3% of the world’s electricity and produce over 200-million metric tons of CO2. These figures are continually growing, driven by the demand […]

True to the analogy of the treasure trove in “Aladdin’s Cave”, many organisations are trying to control a wealth of potentially valuable data that is piling up in gigantic, unstructured heaps. For many companies, the current approach involves sliding open the rocks surrounding the cave entrance, throwing in the latest set of data, and sealing […]

There are multiple keys to having a successful application-specific integrated circuit (ASIC ) design cycle. This article presents key elements, showing that at every stage there are important considerations which interact with other stages. Communication between the designer and customer through the whole cycle is important so that issues can be discussed and resolved. […]

The purpose of testing an optical fibre cable link following installation or before turn-up is to prove that the fibre link and all of its components meet specifications, and that the installation has been carried out as per industry required practices. Test results can reflect that splice comply with specifications, and that cable/link losses […]

Spectrograms are generated by representing the level values of the measured spectrums by different colours and displaying them line by line. This produces an image that provides frequency and time information simultaneously. Displaying the results becomes difficult at high time resolutions. A measurement over a period of just 10 ms with a resolution of […]

Argo floats are autonomous “robots” of the ocean, collecting valuable upper-ocean physical oceanographic information – notably pressure, temperature and salinity data. The floats are deployed from research vessels or vessels of opportunity globally and collect profiles of the upper 2000 m of water column every ten days, resting at a park depth of 1000 […]

In this article we will examine fibre to the office (FTTO) technology, its benefits and a practical application featuring 1000 user ports.The number of applications running on networks, and herefore required IP convergence, keeps increasing each year. FTTO provides an ideal basis for the growing flexibility needs of today’s buildings. An FTTO approach to in-building […]

Fibre to homes and businesses will not be a simple step-change in the quality of our internet connections. It will lead to something entirely new… The introduction of fibre optic connections to homes and businesses in South Africa isn’t a mere incremental enhancement in the quality of our internet connections. With speeds that are […]

Charles Darwin once claimed that it was not the strongest nor smartest of a species that survived, it was those most adaptable to change. What is this change? Let’s call it technological evolution and let’s explore it as a changing process, an evolving process, in a world where the only constants are engineering change […]
